Interaction between modules
A typical bay with apparatus control function consists of a combination of logical nodes or
functions that are described here:
•
The Switch controller (SCSWI) initializes all operations for one apparatus. It is the command
interface of the apparatus. It includes the position reporting as well as the control of the
position
•
The Circuit breaker (SXCBR) is the process interface to the circuit breaker for the apparatus
control function.
•
The Circuit switch (SXSWI) is the process interface to the disconnector or the grounding
switch for the apparatus control function.
•
The Bay control (QCBAY) fulfils the bay-level functions for the apparatuses, such as operator
place selection and blockings for the complete bay.
•
The Reservation (QCRSV) deals with the reservation function.
•
The Protection trip logic (SMPPTRC, 94) connects the "trip" outputs of one or more protection
functions to a common "trip" to be transmitted to SXCBR.
•
The Autorecloser (SMBRREC, 79) consists of the facilities to automatically close a tripped
breaker with respect to a number of configurable conditions.
•
The logical node Interlocking (SCILO, 3) provides the information to SCSWI whether it is
permitted to operate due to the switchyard topology. The interlocking conditions are
evaluated with separate logic and connected to SCILO (3).
•
The Synchronism, energizing check, and synchronizing (SESRSYN, 25) calculates and compares
the voltage phasor difference from both sides of an open breaker with predefined switching
conditions (synchronism check). Also the case that one side is dead (energizing-check) is
included.
•
The Generic Automatic Process Control function, GAPC, handles generic commands from the
operator to the system.
The overview of the interaction between these functions is shown in Figure
